just use the notification NB6 (Firebase library)

NB6 - Notifications Builder

Background For a long time there were two ways for B4A developers to show notifications: - Simple notifications with the built-in Notification object. - More complex notifications with barx's NotificationBuilder library. Thank you barx for all your work!!! The notifications features changed a...

Thanks for the Quick response

Will the notification on the promotion or any other notice be sent from the admin panel?

so beautiful. i like the backend solution a lot. actually, i am learning web design right now because i want to be able to use web backend and b4x together. from what i see is you are using bootstrap and w3 css. very nice!

i am planning to create a dashboard using bootstrap on Atom and use it as a backend tool for my next b4a mobile app. lot of work to do and new stuff to learn but i am making very good progress and the most important thing it is very interesting and i enjoy it

keep the good work!

first of all Thank you for your kind words

the UI design (html + css + JQuery) is pretty easy, the challenging part is the asp.net (c# or Vb.net ), the back-end you saw was built in asp.net vb

if you need any help please let know and i will do my best to help

Do you mean handling the data that are coming from the MySQL database? javascript should also be able to do the work right?
all charts, data read/write, animations, site behaviors should be able to do using javascript too as far as i know.

The asp.net is used to handle MSSQL + the show the UI design
the asp.net has 2 components :
1- vb or c# (the code behind) meaning it's the code that happens in the background without enabling the user to see for example the connection string to the database or the code when you click a button
2- html design is the UI that the user is able to see

as for the connection using the java script, it's most definitely wrong because when you press (CTRL + U , view page source) you could see the site html source and the javascript will show so your connection string will appear and that will definitely make your site hackable 100%

You can use jquery and/or ajax to call the web service. The browser view source won't show the connection string or business logic.

but it will show the function name and that's considered a big flaw and hackable.

the ajax call example :

Ajax:

        type: "POST",
        url: "PayBills.aspx/LoadPayments",
        data: { cod_client: client, page: _page },

The function : PayBills is exposed which means now the hacker know what function you use, and it's really bad to show the functions to the public
Thats why Microsoft invented (Code behind) when they did the asp.net creation

You may need to handle the authentication and authorization using session, token and/or API key.

The session expires after 20 minutes if there is no activity and resets which means you will lose the information and that's wrong, becuase lets say the user is in the cart screen and didn't press the checkout for 20 minutes, all his information will be lost.

the best solution :
*Using the code behind in asp.net
*User controls in MVC asp.net

Yes, there are pros and cons between both technologies.
To keep session alive, you can use cookie which you can control the lifetime.
You can also use cookie and session to keep the items in the cart. You can also use timer running in the background to send(or backup) the cart items to store in server (may not good solution, I am not sure).

The use of JavaScript is for front-end development and ajax provide better user experience where not whole page is send to or refresh from the server.

on that i 1000% agree

Bad solution because you will distroy the server bandwidth + if you want to store as a #Temp table in sql it will lock the sql database because the #Temp will never be droped unless you do the funtion drop table which means you did nothing

The use of JavaScript is for front-end development

JavaScript was originally created for the UI experience then they started developing it to try to make a server development language and made a separate language (JQuery) which made it worst lol

and ajax provide better user experience where not whole page is send to or refresh from the server.

you are referring to the post back : the solution is to use Update Panel and it will never refresh the page

I started developing web applications asp.net since 2009 and let me tell you it sucks lol, that's why i love the mobile applications development alooooooot more

I think MS is dropping support of WebForms in favour of .NET Core which is not using Code-behind.

They are not dropping but focusing more on the new technologies like MVC and .net core

Since we are on B4X, the best would be to avoid using ASP Net, VB Net, C# and use B4J (maybe ABMaterial).

It would also be easier for many B4X.com members.

I developed since Classic ASP 3.0 if you have heard before (page file ended with .asp extension) then started with ASP.NET with .NET 2.0 using Visual Web Developer (It has not yet name Visual Studio .NET) and it was not free to use. When things evolved started with .NET 4.0, it has become more and more heavier. Personally, I really like Classic ASP (it is very fast) and ASP.NET version 2.0 (it is simple, no aspx.cs.designer) until everything has become a mess today. People criticize PHP spaghetti's code but noone say about C#. Recently I quit because I could no longer stand to maintain those messy C# code and SQL queries written by previous developers.

spaghetti's code

Please, do not offend spaghetti (although many other types of pasta are better, such as: "Rigatoni", "Fusilli", "Pennette", ... )

Sorry forgot you are from Italy. I like pizzas. ?

Xfood · Jan 19, 2021

don't forget the tortellini ?

aeric · Jan 19, 2021

By the way, some legacy C# .NET 4.0 code and SQL queries with a lot of #temp tables written by my previous colleagues are even worst than pasta or whatsoever. Those "noodles" are separable but not the code I mentioned which is like a messy knotted rope balls with a timebomb bonded inside together with a dynamite attached on it made by a few amateur bomb makers with different level of skills. Can you imagine how to reverse the code to understand the logic. Not to mention about the simplest documentation in the world which doesn't do any help at all.
Sorry, for out of topic.
